report predicted a future for the industrial mass production of plastic houses but recognised that the resulting standardisation would be problematic for marketing them as private houses.



The plastic houses that were realised proved that plastics were fundamentally suitable for use in architecture and that in terms of structural stability, thermal performance and durability, they could be used in place of conventional materials. Their use was restricted primarily to single-storey buildings. Beside the production of entire buildings that were delivered as prefabricated products equipped with integrated fittings, further applications included individual components made 1.6

of plastic, for example sandwich panel façade elements, prefabricated ­sanitary cells and roofing elements. The experimental test structures from this period addressed many key considerations and together made a significant contribution to the future of plastic architecture. The structural potential and technical performance of fibre-reinforced plastics was of particular use for wide-span roof structures. A series of engineers devel-
